[Gnuplot-py-users] Patch for mishandled filenames

[Noel O'B. <no...@ca...>]

Dear all,

Please find attached a patch for the following problem:

Problem:

On Windows, if your user name contains an apostrophe, the use of
temporary files causes an error, as gnuplot uses apropostrophes (i.e.
single quotes) to delimit the filename.

gnuplot> plot 'c:\docume~1\noelo'~1\locals~1\temp\tmpcxnwsm' notitle
                                   ^
         invalid character


Solution:

If you replace the single quotes with double quotes, gnuplot is happy
with the apostrophe but misinterprets the backslashes as escape
character sequences.

gnuplot> plot "c:\docume~1\noelo'~1\locals~1\temp\tmpcxnwsm" notitle
              ^
         can't read data file "c:docume~1
oelo'~1locals~1 emp     mpcxnwsm"

....so you need to also replace all of the backslashes with forward
slashes.

gnuplot> plot "c:/docume~1/noelo'~1/locals~1/temp/tmpcxnwsm"
notitle            

**Success!!**
